Most people won't notice it, but we will have a lunar eclipse tonight, visible from anywhere in Australia (weather permitting, of course) — and also from New Zealand, most of the Pacific, Alaska, China, parts of India and most of Russia. The continental US sees only part of the eclipse, with the Moon setting before it ends.
A penumbral eclipse happens when the Moon goes through the penumbra of the Earth, the area of "partial shadow" around the main shadow of the planet. Viewed from the Moon, this appears as a partial solar eclipse (an umbral eclipse is seen from the Moon as a total solar eclipse).
In eastern Australia, the eclipse starts at 23:36
AEST AEDT (12:36 UTC), with the maximum eclipse at 01:38 tomorrow morning (14:38 UTC). Visually, you will see one "corner" of the full Moon clearly darker that the rest of the disk. More information and a visibility diagram can be seen at the HMNAO eclipse's website.
